Determine the value of F
l will give BRAINLIEST.​

10 N

Explanation:

From the diagram,

Applying the principle of moment,

Sum of clockwise moment = sum of anti clockwise moment.

Assuming: the 10 N is placed on the 5 cm mark, F is placed on the 40 cm mark, The 25 N is placed on the 10 cm mark, the 30 N is placed on the 75 cm mark, and the 40 N is placed on the 80 cm mark.

Therefore,

10(50-5)+F(50-40)+40(80-50) = 30(75-50)+25(50-10)

450+10F+1200 = 750+1000

10F+1650 = 1750

10F = 1750-1650

10F = 100

F = 100/10

F = 10 N
